摘要：

An　effective　methodology　is　developed　to　investigate　the　vibration　of　the　sandwich　plate　with　pyramidal　lattice　core.　Equation　of　motion　of　lattice　sandwich　plate　is　established　by　Hamilton＇s　principle.　Displacement　fields　are　expressed　with　a　simple　method,　and　the　natural　frequencies　of　the　lattice　sandwich　plate　are　conveniently　calculated.　The　correctness　of　the　analytical　method　is　verified　by　comparing　the　present　results　with　published　literatures.　The　effects　of　structural　and　material　parameters　on　the　vibration　characteristics　of　lattice　sandwich　plate　are　analyzed.　The　present　method　will　be　useful　for　vibration　analysis　and　design　of　lattice　sandwich　plates.
